Title: Catamaran
Inventor: YAMAMOTO OSAMU
IPC: B63B1/12
Filed: 1990-08-29
Abstract: PURPOSE:To reduce the oscillation during contrary wave, preventing the intrusion into the wave surface even in the high speed navigation in the favorable wave, by setting the width of the vertical sectional surface in the semisubmersible part at the min. width part to 0.3-0.6 or more of the max. width of the vertical sectional surface of the semisubmersible part. CONSTITUTION:The width of the max. width part 14 of a semisubmersible part 3 becomes max. on the sectional surface shown by the line B-B, and gradually reduces from this position to a bow and a stern. Bmax is the value of the max. width part 14 at the semisubmersible part 3, and Bsmax is the value of the min. width part 13 of the semisubmersible part 3. At the bow part, the semisubmersible part 3 is formed to a V-figure shape from the max. width part 14 to the upper and lower edges. Though, when the bow of the semisubmersible part 3 intrudes into the wave surface during the favorable waves, the relative flow speed in the aslantly downward direction inevitably acts on the upper surface of the upper part 3a of the bow part, this phenomenon is suppressed by reducing the apex angle alpha of the upper part 3a, and the apex angle is desirably set to 60 deg. or less. In the high speed navigation in the contrary flow, the wave top is allowed to pass in the upper part by a prescribed distance from the min. width part 13, and then oscillation is reduced. Accordingly, in the semisubmersible part in the rear part, the vertical height (h) from the water level 5 of the min. width part 13 is set to 0.3 or less of the Bmax, and the ratio of Bsmax/Bmax is set in a range of 0.3-0.6.

Title: Non-contact type ammeter
Inventor: MATSUNOBU YUTAKA
IPC: G01R15/18
Filed: 1992-08-27
Abstract: PURPOSE:To provide an ammeter with higher accuracy by shaping a detecting section like the form of a superconducting trochoidal coil, and using a ferromagnetic material for a winding core. CONSTITUTION:When current flows across a sample, current also flows in a Rogowskii coil and magnetic field is generated with a sensor coil connected to the Rogowskii coil in superconducting state. Thus, when a Hall element is laid across the sensor coil, Hall voltage is generated. In this case, accuracy is determined only on the basis of the performance of the Hall element and no accuracy improvement results. For this reason, a coil to offset a magnetic flux generated with the current flowing across the sample is provided, and the Hall element is used as a zero-point sensor entirely free from an error, even when subjected to an influence by external magnetic field. According to this constitution, a clear linear relationship is established between the sample current and cancel current, and highly accurate measurements can be undertaken. Furthermore, a ferromagnetic material is used for the winding core of the sensor coil, and the coil is shaped like a trochoidal form free from flux leak, thereby enabling measurement accuracy to be enhanced.
